If I am found innocent of a crime, will it still be on my record?

Yes. Even if you are never convicted, or you are found not guilty of the crime for which you were arrested, the record of the arrest will still be freely accessible to anyone seeking criminal records or performing a background check. Depending on your jurisdiction, an employer may ask about you about your prior arrest history, in which case you would be obligated to disclose the fact that you were arrested.
